The Obama campaign is criticizing Ludacris' new song.

(CNN) – Barack Obama's campaign sharply condemned rapper Ludacris Wednesday over his new song celebrating the Illinois senator's presidential bid while referring to Hillary Clinton by an offensive remark.

The song, called "Politics: Obama Is Here," was released earlier in the day and refers to the New York senator as an "irrelevant b***h." Ludacris, whose real name is Chris Bridges, also takes aim at John McCain in the song, saying the Arizona senator "don't belong in ANY chair unless he's paralyzed."

The song, which largely celebrates the rise of Obama on the national political scene, also criticizes the Rev. Jesse Jackson and President Bush.

Obama campaign spokesman Bill Burton said Ludacris should be "ashamed of these lyrics."

"As Barack Obama has said many, many times in the past, rap lyrics today too often perpetuate misogyny, materialism, and degrading images that he doesn’t want his daughters or any children exposed to," Burton said. "This song is not only outrageously offensive to Senator Clinton, Reverend Jackson, Senator McCain, and President Bush, it is offensive to all of us who are trying to raise our children with the values we hold dear. While Ludacris is a talented individual he should be ashamed of these lyrics."

Obama has praised Ludacris in the past and the two men sat down privately in 2006 together to discuss ways to empower youth.
